About
Deduplicate text by lines for faster cleanup of lists: keywords, emails, IPs, IDs, and more. Great for preparing inputs for scripts, spreadsheets, and automation. Runs locally in your browser.
Use cases
- Remove duplicate keywords before uploading to an ad platform.
- Deduplicate a list of IDs copied from logs.
- Clean and sort a list before feeding it into a script.
Common pitfalls
- Windows line endings (CRLF) can create invisible differences—normalize inputs if needed.
- If your list is comma-separated, split it into one-item-per-line first.
Examples
Input
a\nb\na\n
Output
a\nb
FAQ
Are empty lines kept?
No. Empty lines are removed by default.
How is sorting done?
Sorting uses lexicographic order (localeCompare). For numeric sorting, consider zero-padding or post-processing.
Is it case-sensitive?
Deduplication is typically case-sensitive unless the tool explicitly normalizes case. If needed, convert case first.
Does it trim whitespace?
If trimming is enabled in the tool UI, leading/trailing whitespace will be removed before deduplication.
Limitations
- Deduplication is line-based; it won’t deduplicate items separated by commas on the same line.
- Sorting is lexicographic; numeric sorting may differ from expectations.
